I just ran 11.9 at 118 in 90 degree and humid weather. Hoping for mid 11s with a better DA. Stock turbos are starting to act up lol. Fastest prior was 11.8 @ 118

2nd gear launches are for the rwd guys. Xi should be launching in 1st all day.

alrighty, when do you shift? 1st in the 6at is so short it's like, if you don't shift prior to when you want it to shift then you're already too late.

Just go into sport mode and let first auto shift to second or you're right, you can miss it. Then for the rest of the fears use manual mode to shirt shift slightly before redine.

Hey guys, first post here. I have a 2011 328i manual xdrive with a bms powerbox and four mods to air intake. Air scoops, kn filter, charcoal delete and silencer delete. I just ran a 14.6 1/4 mile and a 6.45 of to 60. 68 degrees out and mild humidity. Gtech says I'm putting 196hp to the wheels, so about 238 crank. 93 octane with booster, half tank. Sounds about right to me. What are your thoughts?

Try launching in 2nd, i always thought 1st as well but it depends on your mods.
I have dci, mhd custom hitting 19psi, and dps with about e45 stock pump

My fastest ever in a 1st gear launch was 12.598 @110
I tried 2nd once for my last run right before the track closed and got 12.52 @112

I might be able to hit 12.4 with 2ND gear launch

I've launched my xi on a deserted street deep deep in Mexico and it did just fine back then.. pulled off the spot hard but if it's gonna substantially hurt the drive train then idk

2nd gear launch is extremely hard on the drivetrain.

I agree. 2nd gear launch is very hard on the transmission but actually easier on the rest of the drivetrain due to the reduced output torque of being in second gear.....never launch awd hard in 2nd !!!

Going to take my n55 335 xdrive to the track next weekend. What times should I shoot for?

93 gas, jb4, downpipes, intake

I was hoping for high 12's

Yep, should be able to do that without too much issue. It will need more octane to get lower or a bigger turbo.
